Application July 22, 1955, Serial No. 523,661

1 Claim. (Cl. 81-55) .is desirable because often the two nuts stick together and this wrench takes care of that difficulty.

Another important object of the invention is to provide a wrench of the character stated which is of'simple construction and capable of being manufactured and retailed at a low monentary figure.

Still another object'of the invention is to provide a wrench of the character stated which is positive acting and not susceptible to the ready development of defects.

These and various other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawing:

Figure 1 is a side elevational view of the tool.

Figure 2 is an end elevational view looking at the handle end.

Figure 3 is an end elevational view looking at the socket end.

Figure 4 is a fragmentary longitudinal sectional view through the assembled structure.

Figure 5 is a fragmentary longitudinal sectional view through the shell.

Figure 6 is a side elevational view of the shaft.

Figure 7 is a fragmentary elevational view of the head of the shell holding handle.

Figure 8 is a fragmentary elevational view of one end of the shaft turning handle. 7

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 10 denotes a shell having a bore 11 therethrough. One end, that is the smaller end of the shell 10 has a polygonal formation 12 at its outer side. The other or large end of the shell 10 has a cavity 13 therein and to which the bore 11 opens and the interior of this end of the shell 10 is provided with a-polygonal nut engaging formation 14, as is clearly shown in Figure 5.

"ice

An elongated shaft 15 has a. socket head 16 at one end, containing a polygonal shaped socket 17 while the other end of this shaft 15 is provided with a squared reduced end 18. In assembling the aforementioned parts, the shaft 15 is slipped through the bore 11 so that the squared end 18 will protrude beyond the polygonal formation 12 of the shell 10, as shown in Figure 4. This places the socket head 16 within the cavity 13.

Before the polygonal formation 12, there is an elongated handle 19 having a polygonal head formation 20 for disposition over the polygonal formation 12 for the purpose of holding the shell 10 stationary while the shaft 15 is being turned.

The shaft 15 is also provided with a handle 21 which has a square opening 22 in one end thereof to receive the squared end 18 of the shaft 15.

Thus it can be seen that when this wrench is disposed in place, the polygonal formation 14 at the outer end of the cavity 13 is placed over the outer nut on the dual wheel and the socket end 16 then engaged over the inner nut. By holding the handle 19, the shell 10 can be held stationary while the shaft 15 is rotated by the handle 21 in order to turn the outside nut and remove the same.

While the foregoing description sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention what is claimed as new is:

A wrench structure for dual wheels havinginside and outside nuts, comprising a shell having a'wrench end for engaging the outside -nut and a supplemental wrench for engaging the inside nut, manual means for holding the shell and manual means for actuating the supplemental inside nut wrench, said supplemental wrench consisting of an elongated shaft disposed through the shell and provided with an inside nut engaging socket head, the

other end of the shaft being provided withv a laterally disposed handle, said last mentioned end of the shaft being provided with a polygonal shaped portion, said handle being formed with a polygonal shaped opening for detachably receiving the polygonal shaped portion of the shaft.
